Abstract: ELECTROACOUSTIC TRANSDUCER          Abstract A transducer embodying the present invention is assembled on a discrete electrically conductive frame that has been formed to provide both leads and a backplate.  An integrated circuit chip is bonded to one of the leads, and a dielectric inner housing member is molded about the backplate and the portion of the leads adjacent to it.  The inner housing member encapsulates the chip, embraces the perimeter of the backplate, and provides a cylindrical opening that extends on each side of the backplate. conductive outer housing member is subsequently molded about the perimeter of the inner housing member, and a spacer, electret diaphragm assembly, and conductive gasket are sequentially positioned in the opening on one side of the backplate.  Conductive front and back covers are thereafter bonded to the outer housing to close the opening and to complete a conductive enclosure that provides electrostatic shielding for the transducer.  In addition, electrical continuity is provided between a metalized surface on the electret diaphragm and the conductive enclosure by means of the gasket.

Abstract: ABSTRACT           A heat pack and a process for its preparation are described wherein the heat pack comprises an earth-like mass between two outer layers surrounding the mass and the two outer layers are joined together by means of holding fibers uniformly distributed over their entire surface area.  The joining of the three layers may be effected by a needle bonding process known in the needle tufting process of the textile industry. Webs of the three-layer system needle bonded in this manner are cut into pieces according to their application, thereby forming the heat packs as such, and packaged into foil bags in which the heat packs may be stored and heated.

Abstract: IMPROVED WALL PANEL CLIP              Abstract of the Disclosure An improved wall parel clip includes a retainer plate and a  hook  member  extending  from  the  retainer plate for insertion into a slot to retain a wall panel against  an upright.  The hook forms a  notch  having  a narrow opening and a wider inner width. The surface of the hook adjacent the narrow opening engages a surface of the upright when the hook is positioned in the slots so that a portion of  the upright  penetrates into the slot. Engagement of the hook with the  surface of  the upright  resists  inadvertent  movement  of  the  clip relative to the upright to retain the panel in position on the upright. The dip preferably includes a plurality of  such  hooks  projecting  from  a  spacer  plate  that extends from the retainer plate. The width of the spacer plate is preferably approximately equal to the thickness of a panel to be installed upon the upright so that when the hooks are engaged with the slots, an outer edge of the spacer plate is engaged with a surface of the upright so that the hooks and edge of the spacer plate cooperate to firmly  engage  the  clip  upon  the  upright  while  the retainer plate retains the panel adjacent the upright.

Abstract: Abstract A process and apparatus for forming a glass pane having an upper filter band, and possibly both an upper and lower filter band.  The glass pane may comprise a lamina of a laminated safety glass for use as a windshield of a vehicle.    In the process filter strips are applied to a glass sheet as the glass sheet is moved through a chamber.  The filter strips are applied as a family of filter strips which extend continuously along the glass sheet in the direction of its movement.  The filter strips of the family are spaced apart laterally.  Each filter strip may extend along a straight path, or the filter strips may be of repeating arcuate outline or of sineshaped outline, for example.  The filter strips between a pair of marginal filter strips are of a width that may be greater than the width of the marginal strips, and the filter strips may vary in width along their continuous length.  The process envisions subdividing the glass sheet into a multi-plicity of blanks, each of which includes a part of one or two adjacent filter strips, and cutting a glass pane from the blank.

Abstract: CONTROL SYSTEM FOR MANIPULATOR APPARATUS  WITH RESOLVED COMPLIANT MOTION CONTROL                 Abstract of the Disclosure A control system for manipulator apparatus having a manipulator arm movable in a plurality of axes utilizes resolved compliant motion control to improve servo response character-istics.  The position and velocity of the manipulator arm are controlled using load modeling to account for compliance in the arm and to synthesize feedback signals respresenting move-ment of a remote point of the arm to provide a loop bandwidth greater than is possible using feedback signals from inner less remote points of the manipulator that are closer to the drive points.  The feedback signals are derived using predeter-mined combinations of force related feedback signals from the axis drive arrangements and position and velocity feedback signals of the manipulator apparatus at points closer to the main drive and support structure of the manipulator and before certain compliant portions of the manipulator arm.  To further enhance response and control of the manipulator arm, load modeling is also used to provide controlled deceleration before the manipulator arm is brought to a stop during work operation.

Abstract: ABSTRACT OF THE DISCLOSURE           A process for preparing .alpha.-alkyl amino acids by enantioretentive .alpha.-alkylation of .alpha.-amino acids is described.  The process comprises the steps of con-verting an optically active acyclic .alpha.-amino acid to a 2-aryloxazolidinone compound in which the non-hydrogen substituent at the 4-position and the aryl group are in a cis relationship, stereospecifically alkylating the 2-aryloxazolidinone by first forming an alkali metal enolate by reacting the oxazolidinone compound with a strong base at greatly reduced temperatures followed by reacting the enolate with an alkylating agent, and generating the .alpha.-alkyl-.alpha.-amino acid from the alkylated 2-aryloxazolidinone by alkaline hydrolysis to open the ring followed by hydrolytic or reductive removal of the protecting group.  The products are bioactive compounds including some useful as therapeutic agents.

Abstract: ABSTRACT OF THE DISCLOSURE         Finely divided lime, at any degree of slaking, is introduced in a steady stream into an agitated reactor designed to produce pellets or aggregates.  Concentrated acetic acid is simultaneously introduced in a steady stream at a rate equal to the chemical combining rate required to produce calcium magnesium acetate.  Water content of the reaction stream is critical; the mol ratio of water, including water of neutralization, to the calcium magnesium acetate product must fall in the range 3.3 - 7.0 in order to form the desired pellets and to avoid sticking, caking, and dust emanation from the reactor.  Product pellets are drawn off in a stream from the reactor and dried for use as a non-polluting roadway and walkway deicer.  Traction agent is optionally incorporated into the deicer pellets by introducing a steady stream of traction agent to the reactor simultaneous with raw materials introduction.  Magnesium-to-calcium ratios greater than one are achieved by blending dolime with magnesium-rich ore.
